KING UITON, OF SALEM, MASSACHUSETTS.

RAI LWAY-CAR.

SPECIFICATION forming part of Letters Patent No. 440,729, dated November18, 1890.

Application filed July 24, 1890. `Serial No. 359 ,737. (No model.)

To all whom, it may concern:

Be it known that I, KING UPTON, of Salem, county of Essex, State ofMassachusetts, have invented an Improvement in Cars, of which thefollowing description, in connection with the accompanying drawings, isa specification, like letters on the drawings representing like parts.

'l'his invention has for its obj ect to improve the construction ofcars, whereby telescoping of the same in collisions may be avoided.

My invention consists in a car-frame having vertical diagonal planes ofweakness located at or near opposite ends of the car and substantiallyparallel with each other for the purpose specified.

In the drawings, Figure I represents an under side plan view of acarframe embodying my invention, and Fig. 2 a modification to bereferred to.

The car-frame herein to be described consists of the usual side andcenter sills a and the end sills a', herein shown as extending fromopposite corners of the car diagonally inward and across to the oppositeside of the frame, and to which are secured the sills a2 a2, havingframed to them the corner-sills a3, the said sills a2 and a3 forming, asherein shown, triangular sections A, entirely independent of the mainbody-traine, to which they are secured, as herein shown, by bolts 2, tocomplete the rectangular frame of the car. The sides and roof ot' thecar are similarly framed, to thereby present substantially parallelvertical planes of weakness at or near the ends of the car, as indicatedby the dotted lines @cac on the drawings. The abutting face of thetriangular-shaped end sections and the main body are preferably fittedwith metallic or other face-plates p, through which the bolts 2 or otherconnections are passed, and which act to sever the said connections topermit the end sections to slide freely to one side in case of a violentshock.

It will be seen that in the event of a collif sion between two or morecars framed as herein shown the triangular sections A will break awayfrom the main body-frame at the diagonal planes of weakness,(indicatedby dotted lines .fr 00,) permitting the cars to slide by eachother sidewise, instead of telescoping each other with the usual fatalresults, as is common with cars as at present framed.

I have herein shown the triangular sections A as framed entirelyindependent of the body-frame of the car and secured thereto by bolts;but I do not desire to limit myself to this construction, as thetriangular sections may be framed to the body-frame by mortise and tenonor in any way to present a diagonal plane of weakness, as described.

In Fig. l the bolts 2 are shown as extend ing longitudinally of thecar-body; but in Fig. 2 the bolts are shown as passing through the sillsat right angles thereto.

I claiinl. A car-frame having two vertical diagonal planes of weaknesslocated one at or near each end of the car and extending from side toside thereof, substantially parallel with each other, substantially asdescribed.

2. A car-frame having substantially triangular-shaped end portionssecured thereto, the abuttingfaces ot' the said frame and end portionsbeing fitted with metallic or other face-plates, substantially as andfor the purpose specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

KING UPTON.
